Questions

How big is the PCB v1 PCB?

It measures 50 × 40 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCB v1 use?

9 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the PCB v1 KiCad files?

From the buttonbugs/Stuffed-Crust repository on GitHub, at the commit this page was made from: the board is PCB/PCB_v1.kicad_pcb and its schematic ESP32_PCB/ESP32_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCB v1 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
